The developer is still transitioning Adblock Plus to Firefox 57, so much of the functionality has been temporarily compromised. In the meantime, I recommend not upgrading to Firefox 57 or reverting to Firefox 56 and using Adblock Plus version 2.7.1 to restore full workability. Addon rollback works for other addons annihilated by WebExtensions as well. Just make sure to disable Firefox automatic updates and set any Firefox-57-incompatible addons to update manually. Disabling addon compatibility checking and/or addon signature checking through about:config may be required, but I don't believe so.

poco funcional la instalacion

Still work...but another better choice out there....

it has been one of my favorite add-ons for Firefox, sites load faster without having to download all those ads, and the interface looks cleaner.
one thing that the previous version had that was better than the new version, is that you could whitelist a specific part of the site while allowing what you wanted to go through. now I have the problem in some sites that Adblock mistakenly blocks some essential parts of the site, and the only way to see that essential, is by letting all the ads go through.
its all or nothing, either you get infested by ads all around, or see a broken website lacking essentials.

Nem mindig véd a reklámoktól.

Used to be a 5 star but now, if I want to watch some clips on youtube (specially Jimmy K), the video will come up, but only the voice, no image and I've reported this but 3 months later, still no fix.

So I decided to try AdBlock (the one with the "hand" logo) and it's been fantastic, better than ABP. And ultimately, they're the same but AdBlock is better now because of that .

Version 3.0.1 didn't block custom objects.

Der Suport ist lausig, ich habe Probleme mit meinen Postfächern Web.de und GMX.net und lösen soll das ein Forum.

Дополнение отличное, но есть одна проблема. Не работает функция "Заблокировать элемент", проверял на нескольких компьютерах.

Firefox 57.0

This is not Ad-Block's fault but it's yet another thing that Firefox Quantum has screwed up. Quantum nearly bricked my laptop when using ABP. Leaving me pretty screwed now.

还是以前能用中间键控制启用方便些。

Used to be fairly happy with it,
apart from things like having to set my filters again and again after closing and re-starting Firefox,
but with the FF 57 update it stopped working completely.

Now using the other well known one (I'm sure you'll find it when searching ;)

Nowadays it allows opening of new tabs of ads without blocking them.

Add on cant be downloaded due to connection failure

Great but has a huge impact on CPU and memory usage. You are bleeding your userbase to uBlock Origin primarily for that reason.

downdgrade addblock 2.9.1. is the best

This add-on is no longer worth using. The updated UI is horrible, complete with social links added in. The user functionality has been seriously reduced, a list of commands is gone and been replaced by an inept alternative. Until the latest update has been reverted, do not use ABP.

EDIT: Turns out the developer is right, this isn't the fault of the add-on dev but mozzila themselves. I will be using an earlier version of firefox to combat this.

I hope, this 57+ update is not completed. Where detailed blocked list on page? Element hiding helper not work anymore, probably cause of WebExtension ADB update.

The Blockable Items Window must back!
Adblock better than ublock because of The Blockable Items Window show links in real time.

It would certainly help if you could at least add the option to report what filters are triggered on a specific site.
why? Firefox's add-on site just had an overhaul and I'm getting the feeling that a 'rogue' filter is currently screwing it up (which is undiagnosable with the current interface) and the added tab to the developer-tools is PRACTICALLY nonfunctional. (no means for sorting the items means I have to scroll a lot to check if there is any rule being misapplied, as it could be anywhere on the list)
